The Times of London has a new report today on the bloody wages of jihadi recidivism:

At least a dozen former Guantánamo Bay inmates have rejoined al-Qaeda to fight in Yemen, The Times has learnt, amid growing concern over the ability of the country’s Government to accept almost 100 more former inmates from the detention centre.

The Obama Administration promised to close the Guantánamo facility by January 22, a deadline that it will be unable to meet. The 91 Yemeni prisoners in Guantánamo make up the largest national contingent among the 198 being held.

…Geoff Morrell, the spokesman for the Pentagon, said: “This is a large question that goes beyond the issue of transferring detainees. The bulk of the remaining detainees are from Yemen and that has been the case for a long time. We are trying to work with the Yemeni Government on this.”

The US Government issued figures in May showing that 74 of the 530 detainees in Guantánamo were suspected or known to have returned to terrorist activity since their release. They included the commander of the Taleban in Helmand province, Mullah Zakir, whom the British Chief of the Defence Staff, Sir Jock Stirrup, called “a key and seemingly effective tactical leader”. Among others who returned to terrorism was Abdullah Saleh al-Ajmi, a Kuwaiti who killed six Iraqis in Mosul in 2008.

The number believed to have “returned to the fight” in the May 2009 estimate was double that of a US estimate from June 2008. US officials acknowledged that more detainees were known to have reoffended since, but the number has been classified.

“There is a historic trend and it continues. I will only say that we have said there is a trend, we are aware of it, there is no denying the trend and we are doing our best to deal with this reality,” Mr Morrell said.

Officials said that a higher proportion of those still being held were likely to return to terrorism because they were considered more of a security threat than those selected in the early stages of the release programme.

In related news, truckloads of explosives have “disappeared” in Yemen:

In an apparently botched surveillance operation, militants driving six trucks filled with weapons and ordnance succeeded in giving security forces the slip as they entered the city, according to local media.

The revelations came as western diplomatic missions in Sana’a went into lockdown following threats from al-Qaeda’s Yemeni affiliate, which has taken responsibility for a failed attempt to blow up an airliner over Detroit on Christmas Day.
